Advertisements I would say "Most reviewers don't get to keep the hardware, and they have a big advantage over you or I in that they may have actually used all the options in anger. Most go to great lengths to avoid subjectivity or bias but some editors may have changed the final review. It wouldn't suprise me if some truthful reviews are not even published so that advertisers are not offended. I also bet that other reviewers are no longer provided advance products as a truthful review has upset the manufacturer. There are factually good reviews and bad reviews - but the reader will often not know that.
